Here you can configure what the Konqueror file manager will do when you click on a file belonging to this group. Konqueror can display the file in an embedded viewer or start up a separate application. You can change this setting for a specific file type in the 'Embedding' tab of the file type configuration.

This box contains a list of patterns that can be used to identify files of the selected type. For example, the pattern *.txt is associated with the file type 'text/plain'; all files ending in '.txt' are recognized as plain text files.
